is window cleaner an acid or base
Most window cleaners are basic. Many have the odor of ammonia. The ammonia odor usually comes from ammonia or some low molecular weight amine. The bottle of Windex I have at home contains "ammonia D", which I think is an organic amine. A bottle of 409 I have at home contains no ammonia but it contains isopropanol (rubbing alcohol) as a grease cutter, along with surfactants and other cleansing agents.
